Celebrities are used to getting exactly what they want. Sometimes, they can be so specific about what they want that they end up having some pretty strange riders. A rider is a set of requests or demands that a performer sets as criteria for a performance.

One of the most famous demands from a rider is Van Halen's request that they have a bowl of M&M's with all of the brown M&M's removed. This may seem like a strange request (and it is), but the group claims that the reason this was added to their rider was to make sure how seriously promoters actually took their requests. If they got their green room and there was a bowl with brown M&M's, it was safe to assume that the important aspects of the performance such as lighting, staging, and security were ignored as well. That may be the case for Van Halen but not every celebrity has the same concerns. Many of them have weird requests because they're total divas.

These celebs have long riders full of strange requests and they are as shocking as they are hilarious. What's even funnier than the things that they ask for on their riders are the things that they ban completely; such as Beyoncé banning Coke products from her dressing room.

You'll be shocked when you see which famous singer banned his ex-girlfriend's music from playing anywhere near his green room! These requests are totally weird and they show just how much of a diva celebrities can be.

15 No Coke For Beyoncé!

According to Beyoncé's contract with Pepsi, she cannot be seen or photographed with any Coca-Cola products so her green room needs to be stocked with only Pepsi products--but she is allowed to have Snapple products.

Her daughter, Blue Ivy, has a rider of her own that includes her drink of choice: organic whole milk.

In addition to Pepsi products, Beyoncé requires steamed broccoli, green beans, spinach, and a baked chicken that should be, according to her rider, "HEAVILY SEASONED!!" with "fresh garlic, season salt, black pepper, and Cayenne pepper".

It is also very important that she have rose scented candles, a CD player, lemon wedges, and tea served in a brand new teapot. Beyoncé may be one of the biggest divas in the business, but her requests are pretty tame compared to some other stars.

14 The Royal Treatment

Britney Spears' rider has changed a lot over the years. Once upon a time, she asked for her green room to be fully stocked with junk food (including Cheetos) she now asks for all junk food to be banned--with the exception of hamburgers without the buns.

In the late 90s and early 2000s, Britney requested Froot Loops, Captain Crunch, and Pop Tarts, and Doritos but as of 2011, she asked for 100 figs and prunes. Apparently Britney is cutting back on carbs. When she performed in London in 2011, she reportedly asked for fish and chips as well as a framed photo of Princess Diana.

According to The Mirror, "Britney adores the monarchy. Diana was in many ways her inspiration." It is possible that she added this strange request because she thought that all British people keep a framed photo of Princess Diana in their rooms.

13 Don't Remind Justin Of His Ex

No one likes to be reminded of their exes but Justin Bieber took it to a whole new level. After Justin and Selena Gomez broke up and before they got back together, the "What Do You Mean?" singer banned all of his ex-girlfriend's music from being played anywhere near his dressing room. We're guessing that he got that changed after they started dating again.

Selena went so far as to ban any staff members with the name "Justin" from working at her shows. These two hated each other so much it's a wonder that they got back together at all!

In addition to banning Selena's music, Justin requests ten luxury sedans, two buses, a private jet on standby, a helicopter to fly him into the stadium, a jacuzzi, a special Indian Yoga Casket and personal masseuse, and exactly 12 white handkerchiefs.

12 High Quality Peanut Butter And Jelly

It turns out that Jay Z is just as much of a diva as his wife Beyoncé is! However, unlike his famous wife, the rapper actually requests Coca-Cola to be stocked in his green room--better keep that away from Beyoncé though! He also demands that his room be stocked with Red Bull, Fiji Water, Vitamin water, and hot tea.

One dressing room is not enough for the "Family Feud" rapper who needs a total of seven dressing rooms that all need to be have a room temperature of exactly 72 degrees.

There must also be a love seat, a large coach with two end tables that absolutely must match. The strangest request on his list is peanut butter and jelly that must be "high quality" because a standard peanut butter and jelly sandwich is not good enough for Jay Z. Jay Z demands quality in every aspect of his life and that includes sandwiches. Isn't that the life?

11 She's Gaga For Cheese

Not surprisingly, Lady Gaga is very specific when it comes to her rider. The "Million Reasons" singer has about a million items on her list including a pack of straws, a TV (along with a DVD player), four unscented candles, an office style chair, one humidifier, three fans, two bottles of green tea, two bottles of white wine, Yves veggie dogs, one container of guacamole, and an entire smoothie station complete with frozen berries and non-fat Greek yogurt.

Oddly enough, she also requests a cheese plate that must be put on ice, and all of the cheeses must be "non-smelly" and "non-sweaty".

The strangest thing on her list is a mannequin with pink hair with a carpet that matches the drapes! Why? We'll never know--and maybe we don't want to know. It's definitely a unique request and it proves that she is just as wacky as ever!

10 A Throne For The Queen of Pop

Madonna has been in the business for a long time and over the years she's been able to figure out exactly what she likes and doesn't like--and it has led to some pretty wacky demands.

The Material Girl has a 200-person entourage which includes yoga instructors and personal chefs, and she requires dressing rooms for all of them.

She also requires an all-vegan menu which may not seem strange at first, but it is when you find out that Madonna is not actually vegan. According to her rider in 2006, she demands "a brand new toilet seat at every gig", along with dozens of white and pink roses with their stems cut to exactly six inches and candles to protect her from "negative glances and mean-spiritedness." When she stays in a hotel, she demands that all of the furniture be removed so that she can have her own pieces shipped in.

9 Basically Taylor

Taylor Swift's rider may not have any outrageous requests on it but it is so predictable that it is actually hilarious. With Starbucks iced caramel lattes, pumpkin loafs, a bag of Kraft shredded cheddar cheese, Kraft macaroni and cheese, Twizzlers, a case of Corona, strawberry Pop Tarts, Smart water, a bag of edamame, Triscuits, two pints of Ben & Jerry's ice cream, and a single avocado, it is as if T-Swift is purposefully perpetuating the idea that she is, for lack of a better word, basic.

Though the "Look What You Made Me Do" singer is one of the most famous singers in the world, she requests Ragu spaghetti sauce for her pasta--surely she can do better than that! Recently it was reported that according to a new contract, T-Swift is actually allowed to destroy the equipment of a paparazzi if they bother her. It looks like she's not shaking it off anymore!

8 No Veggies For Iggy Pop

Iggy Pop's rider is definitely weird but it is exactly what you would expect from one of rock n' roll's most eccentric rockers. It would probably be more shocking if he had normal requests.

Like most other celebrities, he requests different kinds of alcohol but he has a few requests that are not anywhere near as common. Among his many shocking demands, he requires a copy of USA Today to be provided to him and it has to have a story about morbidly obese people in it.

The veteran rocker also requests that cauliflower and broccoli be cut into individual florets...and then thrown immediately into the garbage. Apparently he really, really hates veggies. A few other strange requests are a Bob Hope impersonator and seven dwarves that are "dressed up as those dwarves out of that marvellous Walt Disney film". It doesn't get much weirder than that!

7 She Doesn't Do Stairs

via Pinterest

There are few celebrities in Hollywood with a reputation for being a diva quite like Mariah Carey, and her rider proves it.

The "Touch My Body" singer requires that every room must be draped, with the temperature at 75 degrees. There should a couch with no busy patterns, melon flavoured Gatorade, three bottles of chardonnay, vanilla protein drinks, four vanilla candles, two vases of white roses, warm fried chicken, and sugarless gum.

During one appearance, Mariah actually asked to be surrounded by "20 white kittens and 100 white doves."

The doves were released into the sky but we'll never know what the kittens were for because it was considered a health and safety risk. No kittens for Mariah! It is also mentioned by her rider that she is not a fan of "busy patterns" and she "doesn’t do stairs." Don't we all wish that we had a contract that banned stairs from our lives?

6 Bye Bye Bye, Germs

During their 2013 Legends Of Summer Tour, Justin Timberlake and Jay Z reportedly wanted to create a “gentleman’s club” vibe backstage. What does that include? Well we do know that a roller was hired to roll cigars for Justin, Jay Z, and their entourages.

For his festival tour, the "Cry Me a River" singer had an entire bus that was just for water. When he stays at a hotel, he demands that he have an elevator and an entire floor to himself! His most bizarre request is that he requires someone to disinfect the doorknobs of any backstage venue or hotel he's in every two hours. That's a lot of disinfecting!

Apparently he is very worried about getting sick. During his NYSNC days, he reportedly asked for grilled cheese, mac 'n' cheese, and chicken fingers. Now however, like Britney Spears, Justin wants junk food to be kept far away from his dressing room.

5 Purple Rain And A Purple Room

If there is anyone in Hollywood who we'd all assume to have some strange requests in their rider, it would be Prince. The "Little Red Corvette" singer was known for being eccentric.

In 2004, he required that everything in the dressing room "must be covered by clear plastic wrap until uncovered by main artist. This is absolutely necessary.”

In 2007, he performed a show at the 02 Arena in London and asked the venue's owner to actually build him a five-bedroom house on the grounds, and also required a machine dispensing black M&Ms and an oxygen bar...whatever that is.

At one point he even asked that his dressing room and everything in it including chairs and table be purple. In the 1990s, Prince required a doctor to be backstage to "administer a B-12 injection."

4 Don't Look At Her In The Eyes!

Katy Perry may seem down to earth but she is secretly a total diva. Katy loves flowers but only hydrangeas, roses, peonies, and orchids--but no carnations. It actually says on her rider "ABSOLUTELY NO CARNATIONS."

She also demands a box of Huggies wipes, two cream-coloured egg chairs, a refrigerator with a glass door, a director's chair with her name embossed on it, a cream or pink rug, and she absolutely forbids water bottles, so all tour personnel must use re-usable drinking bottles. At least one of her demands helps the environment!

She also requires a bag of Snyder's Honey Mustard & Onion Pretzel, plastic drinking straws, lightly salted, dry-roasted edamame, tortilla chips, and Pinot Grigio. The "I Kissed a Girl" singer does not allow any staff members to speak to her and she forbids her chauffeur to even look at her in the eyes.

3 Only The Best Pickles For Eminem

via Thrillist

When we were kids, Lunchables were definitely our lunch of choice but since we've become adults we've steered away from cheese and crackers--but not Eminem. Eminem loves Lunchables so much that he demands that 3 turkey & 3 ham with cheese Lunchables be provided for him in his dressing room.

He also requests that 25-pound dumbbells be available to him along with two loaves of bread, Dannon Light & Fit yogurt, seedless watermelon, jumbo shrimps with cocktail sauce, Swiss mild cheddar cheese, and a jar of banana pepper rings.

There must also be 48 Daisani water bottles with absolutely no Evian allowed. He also requires pickles but not just any kind of pickles--Gundelsheim pickles. Only the finest pickles are good enough for Eminem. He also once asked for an entire wooden pond to be built for him backstage and filled with koi.

2 She Needs Three Fidget Spinners

via Pinterest

Danielle "Cash Me Outside" Bregoli hasn't been famous for very long, but she's cashing in on her fifteen minutes of fame by adding some pretty strange demands on her rider. For any appearance that she makes, she requires a $750 per diem, plus $3k to cover personal security costs.

In addition to her payment, she requests that there be a 50 inch TV with Netflix and DVD player for watching House of Wax.

According to the rider, the movie is subject to change but it would be hilarious if she just rewatched House of Wax over and over again. She also requests that three fidget spinners be provided for her as well as five Gildan or Fruit of the Loom brand white tank tops but "ABSOLUTELY NO HANES BRAND". She really hates Hanes for some reason. She also requests four large Domino's pizzas and a fruit platter, with absolutely no pineapple.

1 Life Of Kanye

via Pinterest

Kanye West is an eccentric character so it is no surprise that his requests are just as eccentric as he is.

According to his rider, it is very important that any vase in his dressing room be cylindrical, and all of his towels must be black Versace towels.

He specifically asks for a Genelecs 1031a speaker, which is tricky considering that it was actually discontinued a decade ago. One of the strangest requests on his list is that his drivers must wear clothes made from 100 percent cotton only. Like Beyoncé, Kanye also forbids Coke products from being present in his dressing room for some reason. Maybe he just wants to be more like Beyoncé. Who doesn't?

If you needed any more proof that Kanye was especially particular about his dressing room, you should know that he once made his assistant iron his dressing room carpet because it was "too bumpy".
